Description

Technical Field

[0001] The utility model relates to the technical field of differential housing processing, in particular to a differential housing processing tool capable of engaging multiple holes. Background Art

[0002] The automobile differential is a mechanism that enables the left and right (or front and rear) driving wheels to rotate at different speeds. Its function is to make the left and right wheels roll at different speeds when the car is turning or driving on uneven roads, that is, to ensure that the driving wheels on both sides perform pure rolling motion. The differential housing is a protective component outside the differential, and during the processing of the differential housing, it needs to be positioned by processing tooling to avoid displacement in subsequent processing;

[0003] Traditional differential case processing tooling generally includes a placement table and a clamping assembly. During processing, the clamping assembly is needed to clamp and fix both sides of the differential case placed on the placement table. However, only the symmetrical two sides of the differential case are clamped, resulting in poor overall clamping effect. Displacement still occurs, and it is not convenient to clamp and position differential cases of different sizes. Utility Model Content

[0010] Furthermore, the transmission plate, the mounting plate and the mounting frame are arranged in a one-to-one correspondence, and the mounting frames are distributed in an equiangular circle on the outer side of the placement table.

[0011] Furthermore, a positioning hole adapted to the fixed insertion rod is provided inside the upper end of the placement table.

[0012] Furthermore, the connecting frame is connected to the mounting frame in a sliding manner, and a spring is installed on the upper side of the lower end of the connecting frame.

[0013] Furthermore, the inner end of the spring is provided with a damper which is also located on the upper side of the lower end of the connecting frame.

[0014] Furthermore, an upper electromagnet is installed on the inner side of the upper end of the connecting frame, and a lower electromagnet is provided directly below the upper electromagnet and located on the outer side of the upper end of the mounting frame.

[0015] Furthermore, a limiting rod penetrating the inside of the mounting plate is installed inside the side wall of the electric hydraulic rod, and a limiting through groove is provided penetrating the inside of the mounting plate.

[0016] The utility model has the following advantages:

DETAILED DESCRIPTION

[0024] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0025] like Figures 1 to 3 As shown, a multi-hole engaging differential housing processing tool in the embodiment of the first aspect of the utility model comprises a mounting base 2 which is integrally fixedly mounted on the outer side of the lower end of the placement table 1, and bolts are provided through the inner side of the outer side of the mounting base 2, so that the whole can be stably placed through the mounting base 2, and can be fixed by bolts. During processing, the differential housing can be centered in the middle of the upper end of the placement table 1;

[0026] An electric hydraulic rod 3 located at the lower end of the placing table 1 is provided in the middle of the upper end of the mounting base 2, a connecting block 4 is installed at the output end of the electric hydraulic rod 3, and a fixing ear 5 is fixedly installed at the outer end of the connecting block 4, a transmission plate 6 is installed on the inner side of the fixing ear 5 through a hinge shaft, and a mounting plate 7 is provided on the outer side of the lower end of the transmission plate 6 through the hinge shaft, and the mounting plate 7 passes through the inner wall of the placing table 1, and a mounting frame 8 is fixedly installed on the upper end of the outer side of the mounting plate 7 to form a transmission structure, and the electric hydraulic rod 3 is started to extend the electric hydraulic rod 3 and drive the connecting block 4 to move upward, at this time, the two ends of the transmission plate 6 are respectively rotated with the fixing ear 5 and the mounting plate 7 through the hinge shaft, and the inclination angle of the transmission plate 6 is changed, thereby driving the mounting plate 7 to move in the placing table 1, and then conveniently driving the mounting frame 8 to move in the direction close to the placing table 1, and conveniently driving the fixed insertion rod 11 to move to the top of the threaded hole provided in the flange of the differential housing;

[0027] The connecting frame 10 is arranged inside the upper end of the mounting frame 8, a spring 9 is installed on the upper side of the lower end of the connecting frame 10, and a fixed plug rod 11 is fixedly installed on the outer side of the lower end of the connecting frame 10. A positioning hole 12 adapted to the fixed plug rod 11 is also opened inside the upper end of the placing table 1, and a damper which is also located on the upper side of the lower end of the connecting frame 10 is provided at the inner end of the spring 9. An upper electromagnet 13 is installed inside the upper end of the connecting frame 10, and a lower electromagnet 14 located on the outer side of the upper end of the mounting frame 8 is provided directly below the upper electromagnet 13, so as to facilitate the installation of the fixed plug rod 11 through the connecting frame 10, and the upper electromagnet 13 and the lower electromagnet 14 are arranged on the outer side of the upper end of the mounting frame 8. After the electromagnet 14 is energized, a magnetic connection can be established. The upper electromagnet 13 is turned off through the control panel, so that the upper electromagnet 13 and the lower electromagnet 14 lose their magnetic connection and separate. At this time, the spring 9, which was originally in a compressed state, recovers its deformation and drives the spring 9 to recover, so that the connecting frame 10 slides downward in the mounting frame 8, and then the fixing rod 11 can move downward and be inserted into the threaded hole and the positioning hole 12 opened in the differential housing flange in sequence, and engage with the placement table 1 through the positioning hole 12, so as to facilitate the multi-hole engagement limiting work of the differential housing, which can effectively prevent the differential housing from displacement;

A limiting rod 15 penetrating through the inside of the mounting plate 7 is installed inside the side wall of the electric hydraulic rod 3, and a limiting through groove 16 is provided inside the mounting plate 7. When the mounting plate 7 moves, the mounting plate 7 slides with the limiting rod 15 through the limiting through groove 16. At this time, the limiting rod 15 can ensure the smooth movement of the mounting plate 7.
